1'0 all whom it may concern: Be it known that I, LEONARD B. German citizen of the United States, and a resident of the city of Stamford, county of Fair-field, State of Connecticut, have invented a new and useful Im -which the fol owing is a specification; re erence being had to .the accompanying drawings in which I illustratethe invention as applie to a razor having a triangular blade and coacting bviously, however, many'features of my invention are adapted to razors having blades and coacting parts of other forms.

Figural illustrates an elevation of the device complete. Fig. 2illustrates a vertical sectional view. Fi 3 illustrates a perspec- Y tive view in; lan. ig. 4 illustrates a plan of the under s1 le of the blade. Fig. 5 illustrates a view; of the under side of the razor when a backing-plate is employed.

- straight cross-cut. A represents the I The invention. is characterized-by great simplicity, convenience in use, and low cost. It is also adapted-to both the shearingand handle, and B the guard plate. These parts are or may be eonnected together by interlocking surfaces 0, which are not rigid. On the contrary,when not under pressure the guardlate ma be revolved on the handle. The p ane of t e under side'of the guardlate lies, preferably, slightly below that o the end 0 the handle below the dovetail, so that the pressure of the threaded bolt about to be described upon the blade will clamp all the parts immovably together.

D is the blade. It is preferably, but not necessarily, triangular in shape, each of its edges being sharpened for shaving, and of course the guard-plate B is of corresponding shape. The blade is centrally perforated, as seen at D. r

must both of them pro erly register with the the corners of the blade are adapted to enter, so that the flanges act ascentermg and registing edges are made to groperly conform to the toothed edges of t e uard-plate, and they also act as'sheaths for t e sharp corners of the blades. The blade may be made of material sufiiciently stifi' to elfectively resist the pull of the beard without any backin plate, or, if prefe ed, the blade may be me e of steel so thin t at its flexibility would be objectionable without additional support. In this case I rovide a back plate I, preferabl of metal. t is centrally perforated as at and has the triangular shape of the blade and guardlate, and its corners are preferably shape gutted and registered by the curved flanges .y The ed es of the back plate are recessed, as seen at so. thatthey may not interfere with the cutting edges or the blade.

.The operation is obvious. back plate, if one be used, are placed upon the guard-plate with their corners restmg in the curved flangias at the comers of the and w on in this position they guard plate, all the e gas of the respective parts beinglparallel. The bolt F is then assed through t e perforatlons in the bla e and in the lower .part of the handle and throu h the erforation in theblade-plate, if one be.

lie flat against the back of the blade or of the back plate, as the case may be. The thumb- -nut is then entered within the u per end of thehandle and the threads on t he bolt engaged with it and when screwed up tight all the parts will be rigidly held in position for operation.

It will be noted that the handle may be set at any desired angle relative to the guardplate, thus securing the .shearing out, .socalled, and that if arran ed to project directly over the corners o theguard-plate cured at the two adjacent and apprapriate angles or sides of the blade, or, if pre erred,

right angles to any one of t 'e sides, in which case the straight draw out may be had.

I do not limit myself to the details of construction described and illustrated, for it will be obvious to those who are familiar with this art that modifications may be made.
